Hi,
I'm currently testing some dual socket AMD servers and found that
Turbostat is duplicating the pkgwatt when Perf API is used.
I'm loading only one of the two packages and they both report the same
pkgwatt which is incorrect according to the raw value reported by the
SMI interface.
If I'm adding "--no-perf" the pkgwatt gets the proper value.
I wonder if you have some hints on where the issue could be in the
turbostat code ?
I can make a patch and/or test some if you have hints on a possible reason.
Erwan,
